Comment # 1 on bug 1093378 from Stanislav Brabec

If the device cannot be identified by a textual identification, we either have
to give up and let user to configure it manually, use serial probe (dangerous)
or user assisted check.

I am afraid, that this situation has no easy solution.


I can imagine something like an user-assisted udev rules. Desktop system would
ask e. g.:

USB device with generic FT232 USB-Serial (UART) IC identified

Please select the correct device:
Serial port
Serial modem
QStarz GPS device
Seika Braille display
Watts Up? Pro
...
[checkbox] Remember for this port only
Remember for [1 hour]

Notes:

- It seems that udev currently does not support physical USB port based rules.

- Braille devices need a special support, as these have to be supported during
the installation.
